Summary by Sourcery

Add localized wind-layer altitude and rain labels to the sounding layer controls.

New Features:

  • Display formatted altitude labels for the selected wind layer and precipitation amounts on the rain layer control.
  • Synchronize temperature, altitude, wind, pressure, and rain units with Windy preferences and use them for label formatting.

Enhancements:

  • Improve layer-control styling, active-state presentation, accessibility labels, and conditional rain indication.
  • Refactor class name handling and strengthen unit, formatting, and plugin lifecycle test coverage.

Build:

  • Add clsx as a workspace dependency.

Tests:

  • Add coverage for unit selectors, layer altitude and rain formatting, and Windy preference synchronization during plugin lifecycle.

Summary by CodeRabbit

  • New Features
    • Sounding layer selectors show altitude details for wind layers and rainfall amounts for rain layers with precipitation.
    • Rainfall can be shown in millimeters or inches, and altitudes in meters or feet. These units follow the selected settings and update when preferences change.
    • Rain layers with precipitation are highlighted, with updated styling for layer icons and labels.
    • Missing or invalid rainfall values display as zero; altitude labels use available level information when possible.

Reviewer's Guide

The PR adds unit-aware rain and map-level labels to the Skew-T layer switcher by subscribing to Windy overlay, level, and metric settings, passing formatter-backed values through Redux-connected props, and styling the resulting labels and rain state. It also standardizes class composition with clsx and adds focused utility tests for formatting behavior.

**nitpick:** The docstring says `formatRainAmount` formats rain amounts in millimeters, but the implementation returns inches when the caller selects the `in` unit. The documented behavior no longer describes the function's public contract.

**Suggested fix:** Update the docstring to state that the output uses the requested `mm` or `in` unit and document the conversion and precision rules.

```suggestion
 * Formats a rain amount using the requested unit (mm or in).
 *
 * @param rainMm - The rain amount in millimeters.
 * @param unit - User's preferred rain unit ('mm' or 'in'). Defaults to 'mm'.
 * @returns Formatted rain string in the requested unit. Uses the configured conversion when available, or divides millimeters by 25.4 for inches, then rounds to the configured precision (2 decimal places for inches and 1 for millimeters by default).
```

**nitpick:** The `@returns` documentation shows unitless examples such as `1500` and `5000`, while `formatLayerAltitude` always appends a unit and can return compact values such as `10kft` or `10.4km`. Consumers relying on the documented return shape receive different strings.

**Suggested fix:** Update the return documentation examples to include units and the compact-format behavior.

```suggestion
 * @returns Formatted altitude string with units (e.g. 'Surface', '1500m', '5000ft', '10kft', '10.4km').
```

Walkthrough

The sounding plugin now synchronizes unit settings with Windy store values and events. The SkewT layer switcher displays formatted altitude and positive rain values. The changes also update conditional class composition in sounding controls.

Changes

Sounding units and layer labels

Layer / File(s) Summary
Format values and synchronize units
libs/windy-sounding/src/util/utils.ts, libs/windy-sounding/src/redux/units-slice.ts, libs/windy-sounding/src/sounding.tsx, libs/windy-sounding/src/util/utils.test.ts, libs/windy-sounding/src/sounding.test.ts, libs/windy-sounding/src/test-setup.ts
Adds altitude and rain formatters and unit state, actions, and selectors. The plugin initializes unit settings from Windy store values and updates them from unit events. Tests cover formatter output, unit updates, and listener cleanup.
Pass and display formatted labels
libs/windy-sounding/src/containers/containers.tsx, libs/windy-sounding/src/components/skewt.tsx, libs/windy-sounding/src/style/skewt.less
Passes rain data and formatters to the SkewT layer switcher. The switcher tracks overlay and level changes and displays formatted altitude and positive rain values with updated icon and sublabel styling.
Compose conditional UI classes
libs/windy-sounding/src/components/favorites.tsx, libs/windy-sounding/src/components/wind-profile.tsx, libs/windy-sounding/src/components/skewt.tsx, libs/windy-sounding/package.json, pnpm-workspace.yaml
Uses clsx to compose conditional classes in sounding controls. Favorite selection comparisons use strict equality. The workspace dependency catalog adds clsx.

Merge Risk: ⚪ Minimal · up to 2ff7b

The changes synchronize unit preferences and add formatted layer labels. No concrete merge-blocking issue is established; merge after normal build and test checks pass.

Security Architecture Review

Security architecture risk: 🔵 Low · up to c4f80

The inspected changes display altitude and rain labels without adding privileged operations or interpreting those labels as executable content. The updated caller supplies the new inputs, and subscriptions have cleanup paths. Risk is low, with remaining uncertainty about external event guarantees and consumers outside the inspected scope.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The traced change affects the sounding view within the existing host page. Its inspected paths add display derivation and event-driven unit updates, rather than a new backend operation, tenant boundary, credential capability or privileged sink. This conclusion is limited to the traced consumers.

Trust Boundaries and Controls

  • observed — The new metric handlers accept host event payloads under TypeScript unit declarations without runtime domain validation. Those values enter presentation state and formatter selection; the inspected handlers do not perform authentication, authorization or identity changes.

Resilience and Maintainability Implications

  • inferred — Initialization reads precede listener registration, and no unit reread is shown on reopen. Missed events or invalid unit values could therefore leave stale presentation state or disrupt rendering. External event guarantees remain unresolved, but the inspected effects do not establish a security-control or isolation failure.

A rabbit checks the layers bright,
With rain in inches, rain in mm,
Altitude labels mark each height,
The unit changes settle in,
And clsx keeps the classes trim,
Then hops away beneath the moon.
